The slitting machine blade is mainly used for slitting paper, film, gold, silver foil, copper foil, aluminum foil, tape and other items.
There are more than a thousand types of circular blades for slitting machines. The blades are mainly used for papermaking, paper tube, carton, leather, textile, rubber and plastic, tube cutting, woodworking, electronics, film, gold, silver foil, copper foil, and aluminum foil. , Tape and other items. The materials and precision selected for production also have higher requirements according to the products to be cut.
Circular knife slitting can be divided into tangent slitting and non-tangential slitting.
Tangent cutting means that the material is cut in the tangential direction of the upper and lower disc cutters. This kind of slitting is more convenient for knife setting. The upper disc knife and the lower disc knife can easily directly adjust the position according to the cutting width requirements. Its disadvantage is that the material is easy to drift at the slitting position, so the accuracy is not high, and it is generally not used now.
Non-tangential slitting means that the material and the lower disc knife have a certain wrap angle, and the lower disc knife falls to cut the material. This cutting method can make the material less prone to drift, and the cutting precision is high. But it is not very convenient to adjust the knife. When installing the lower disc knife, the entire shaft must be removed. Circular knife slitting is suitable for slitting thicker composite films and papers.
